From the KRY website - good reminder, imo.

Crystallex submitted the EIS to the CVG and the MinAmb on April 15, 2004. This initiated the final process for environmental permitting for Las Cristinas. The CVG has approved a program of additional environmental baseline data collection, including drilling in the tailings management facility, pit and dump areas to confirm soils and groundwater characteristics, additional acid rock drainage tests, a second phase of socio-economic studies and a characterization of the small scale miners. The results of this additional work was submitted during the second and third quarters of 2004 as addenda to the EIS. In February 2006, Crystallex received rights to aggregate quarry from the Bolivar State Mining Institute (IAMIB). In March 2006 the Ministry of Basic Industries and Mining (MIBAM) formally approved the technical, commercial and contractual complaiance aspects of the Project. Receipt of permits is expected in the near term. The EIS includes a Site Closure and Rehabilitation Plan and an Environmental Management Plan that meets Venezuelan and World Bank standards.
